I agree with Marie - the resources and complexity of metadata required
to archive the separate bits appropriately would very likely make this
untenable. These decisions however, when principles meet resource
limitations, often need making at the time, as resources fluctuate. 

I've only come across one such tape (so far...) which was compiled from
acetate and polyester bits PRIOR TO being recorded onto. Having
unspooled, de-spliced and baked the polyester bits, I was more
comfortable re-splicing (in the analogue domain) and transferring in one
pass than transferring the bits and rejoining using a DAW. I'm aware
that the polyester bits will become sticky again, possibly at some stage
to the point of unplayability, but in the meantime we have a 24/96
transfer made using the best replay equipment available to us, which is
unlikely to be improved on, as is the quality of the tape having been
freshly baked.

What I have seen with this stock is more loss of lubricant, or LOL, or

I really like your thinking here Eric, as I can see you have really
about it and worked with it.

As others have said, there can be problems with each method, attaching
with like, and documenting with leader, details, eventually the lose of
tape and the information if it is not well documented, etc.

I would love to separate it all into stock parts and document that but
reality is....time and person power.  Do we actually have the time to do
of this?  This would also involve for our archive, discussing at great
length a new file format to deal with this as it now becomes more that
object.  These objects have already been alloted a numbering system, as
single file (if they have been preserved)..  Also, do we house them
together?  This also involves somehow extending the shelving, which is
already tight, to fit the 'extra tapes' in.

Archivally and considering the integrity of what we deal with, I believe
practise is to leave it the way it is, but document it thoroughly, which
am sure we all hope, wish and have great hopes in, will remain in the
metadata we are presently creating. (fingers crossed!).

However, there are problems faced by archives and perhaps not places who
not already have a system in place and there are great resources for
them to
go to with ARSC and IASA and FACET, etc.
